Crude Fiber Analysis

Streamline Time And Costs With A Fully Automated Crude Fiber Analysis System

Based on the established Gerhardt FibreBag Method, the new Fibretherm offers the fully automated processing of the tedious boiling and filtration steps for the crude fibre-, ADF- and NDF-determination. Fibretherm has many advantages compared to the standard method. Up to 12 samples can be digested and filtrated simultaneously, which saves precious bench space as well as chemicals. The savings are especially significant for labs with a high sample throughput. The procedure with controlled boiling steps as well as the unique, highly precise filtration mesh of the FibreBags ensures highly precise results. The entire process takes place in a closed system.

FibreBag-MethodUp to 12 samples are each weighted into a Fibre Bag. Just like in the traditional method, the required boiling times and filtration steps are done for all samples simultaneously. When determining the crude fibre content, the non soluble contents as sulfuric acid and caustic potash solution remain in the Fibre Bag. The residue is dried, weighted and then incincerated. The difference between the ash content and the non-diluted residue in relation to the initial sample weight, is the crude fibre content. When doing an ADF- and NDF-determination, the sample is treated with the respective detergents, the remaining substances of the cell structure are specified and determined according to this method as well. Also the calculation is done identically to the crude fibre determination.Since all analyses are conventional methods, it is very important to observe the respective times for the boiling procedures as well as observing the weighing procedures as exactly as possible.

Crude Fiber Analysis – Fiber Bag System
After an extensive trial, a new fiber technique is now made available for the determination of the residue remaining after treatment of serial products with sulphuric and phosphoric acid. The principle is to place a the sample in a bag made of high precision specially treated polypropylene mesh. Six bags are boiled simultaneously in one standard fiber apparatus using a specially designed rack. Filtering is achieved more rapidly under gravity and results obtained are as accurate as the standard method with vastly improved precision. Methods include fiber, ADF and NDF

No top cap to block

Lower blanks

Less plastic per unit

20% lower cost per unit

No maintenance costs

Sixfold increase in throughput
